adult, sexually mature, stage of the insect is known as the imago.
As Lepidoptera, butterflies have four wings, but unlike moths,
the fore and hindwings are not hooked together, permitting a more
graceful flight. A butterfly has six legs; the larva also has
six true legs and a number of prolegs. After it emerges from its
pupal stage it cannot fly for some time because its wings have
not yet unfolded. A newly emerged butterfly needs to spend some
time 'inflating' its wings with blood and letting them dry, during
which time it is extremely vulnerable to predators.
of butterfly are sexually dimorphic. Some butterflies, such as
the Monarch butterfly, are migratory. Butterflies are often confused
with moths, but there are a few simple differences between them,
including colour, habits, and pupating appearance. See the difference
between a butterfly and a moth. Butterflies live primarily on
nectar from flowers. Some also derive nourishment from pollen,
tree sap, rotting fruit, dung, and dissolved minerals in wet sand
or dirt. Butterflies are also pollinators.
